Letters Patent N 92,192, datedvluly 6, 1869.

MECHANICAL MOVEMENT.

The Schedule referred toin these Letters Patent and making part ot' the lame.

' ings as reciprocating the dasher of a common churn.

Figure l is a perspective view ot' my invention. Figure 2 shows the spring-pawl and circular ratchet,

v which is applied to the cord-barrels.

'A is the base, and B C are the upright walls of a frame erected thereon, to give support and journal-v bearing to the barrel-shafts D and P of the barrels E and Q.

Attached to the barrels are weighted'co'rds e q, which are coiled upon the barrels by means of a key, tha?. is placed upon the squared end ot' the barrelsha t.

the. pawl and ratchet operating in a-lnanner similar to that employed in clocks, and vwhich is too well known to require description. Y

Upon the harrel-shaft E is a spur-wheel, H, whose rotation is caused 'by that of the barrel E, through means of the spring-pawland ratchetwhel, as before stated; and the motion ot' the spur-wheel His communicated', through spur-wheels upon the shafts 2, 3,"

and 4, to the pinion iupon the shaft I ot' a y-wheel, J.

The shaft I, at the opposite end to the ly-wheel, carries a spur-wheel, K, engaging another one, L, upon a crank-shafaM.

The pawl and ratchet-wheel F and G prevent there? tation ot' the barrel under the influence Oftheweighted cord without the said barrel, also causing the. rotation of the train of gear-wheels h or fr, as the case may be,l

N is a crank or wrist-arm, which is screwed intot-he crank-shaft M, and whose wrist 'n has connection, by a pitman, O, with the top of the churn dasher-rod o.

The spur-wheel R, upon the shaft P, has movement by similar meansto that of H, and engages a wheel upon av shaft, 5, which, through means ot' another wheel upon the same shaft, canses'the rotation of a shaft, 6,

a wheel upon which engages the pinion 'i of' the iiyf wheel shaft.

The wheels in the train of gear h moved by the wheel H, and the train r moved by the wheel R, each bear such relation to their motive-wheel and'to the other wheels of the' same train, that' the shaftJ Ihas greatly accelerated rotation over either of the shafts D and-P.

It will be seen that the shaft I may receive rotation lfrom either or bothof the barrels E and Q, and as 'the barrels vary somewhat in size, and have connection by Yvery diverse trains of gear (hand r) with the shaft' I,

tl1e,power applied may be much varied by allowing one or the other, Or both weights to act upon the shaft I, and upon any object wth which it is coni" uected.

It will also be seen that' the' length of the stroke of .the pitman O may be regulated by means ofthe screw upon the wrist arm N, the said arm heilig adjusted in Alength byscrewing in or ont of the shaft. y

I claim herein as new and ot my inventioni Thecombination and arrangement ofthe barrels and Q, diverse trains of gears h r, fly-wheel shat't I,

'crankshaft M, and screw-threaded arm N, as and for the purpose described.

I n testimony of which invent-ion,'I have hereunto Y set my hand. v v v y J. M. JOHNSON.
